The ERMGFT350 is a tri-speed fault tolerant transceiver that was designed for rugged use, easy installation and high performance. It is specially suited for mission critical applications in industrial, commercial, and business environments. The device provides redundant paths for 10/100/1000 Ethernet systems with full auto-negotiation and MDI/MDIX. The transceiver should be used with ERM21C, a 21-slot rack mount chassis.
